Nanoparticles from tattoos circulate inside the body, study finds

The elements that make up the ink in tattoos travel inside the body in micro and nanoparticle forms and reach the lymph nodes, according to a study published in Scientific Reports on 12 September by scientists from Germany ...

Nanotechnology pushes battery life to eternity

(PhysOrg.com) -- A simple tap from your finger may be enough to charge your portable device thanks to a discovery made at RMIT University and Australian National University.

New nanostructure for batteries keeps going and going

(Phys.org) -- For more than a decade, scientists have tried to improve lithium-based batteries by replacing the graphite in one terminal with silicon, which can store 10 times more charge. But after just a few charge/discharge ...

Graphene sieve turns seawater into drinking water

Graphene-oxide membranes have attracted considerable attention as promising candidates for new filtration technologies. Now the much sought-after development of making membranes capable of sieving common salts has been achieved.

3D-printer with nano-precision

Printing three dimensional objects with incredibly fine details is now possible using "two-photon lithography". With this technology, tiny structures on a nanometer scale can be fabricated. Researchers at the Vienna University ...

Magnetically levitating graphite can be moved with laser

(Phys.org)—Magnetic levitation has been demonstrated for a variety of objects, from trains to frogs, but so far no one has developed a practical maglev-based actuator that converts some external source of energy into motion. ...
